dbSNP rs778297444: RTF2:p.His297Asn (chr20-56518233-C-A) – ACMG Classification: Uncertain_significance (0 pts)

Variant summary

Our verdict is Uncertain significance. The variant received 0 ACMG points: 2P and 2B. PM2BP4_Moderate

The NM_016407.5(RTF2):c.889C>A(p.His297Asn) variant causes a missense change. The variant allele was found at a frequency of 0.000000684 in 1,461,564 control chromosomes in the GnomAD database, with no homozygous occurrence. In-silico tool predicts a benign outcome for this variant. 12/18 in silico tools predict a benign outcome for this variant. No clinical diagnostic laboratories have submitted clinical-significance assessments for this variant to ClinVar. Another variant affecting the same amino acid position, but resulting in a different missense (i.e. H297Y) has been classified as Uncertain significance.
